"Ink is two times more expensive than French perfume by volume," Suvir says with a chuckle.

He's right: Chanel No. 5 perfume costs $38 per ounce, while the equivalent amount of Hewlett-Packard printer ink can cost up to $75.

So Suvir decided to focus his project on finding ways to cut down on the costly liquid.

Collecting random samples of teachers' handouts, Suvir concentrated on the most commonly used characters (e, t, a, o and r).

First, he charted how often each character was used in four different typefaces: Garamond, Times New Roman, Century Gothic and Comic Sans. Then he measured how much ink was used for each letter, using a commercial tool called APFill® Ink Coverage Software.

Next he enlarged the letters, printed them and cut them out on cardstock paper to weigh them to verify his findings. He did three trials for each letter, graphing the ink usage for each font.

From this analysis, Suvir figured out that by using Garamond with its thinner strokes, his school district could reduce its ink consumption by 24%, and in turn save as much as $21,000 annually.
